If a invasive species were to intervene in the food web then it would break the web because it if were to kill the species it attacked then the web would be broken and a native species might also do the same.
Answer:
there would be less birds.
Explanation:
If the population decreases the birds are dying. Therefore leaving the planet with less birds.
Migratoin is not always temporary so the anser is false
Answer:
A. If the aerobic pathway—cellular respiration—cannot meet the energy demand, then the anaerobic pathway—lactic acid fermentation—starts up, resulting in lactic acid buildup and "oxygen debt."
C. After about 90 seconds of intense exercise, the muscles become depleted of oxygen, and anaerobic respiration can no longer function to produce ATP, resulting in "oxygen debt."
Explanation:
There are two sources of carbohydrates in the human's body for energy (ATP) production. 1) Creatine phosphate and 2) Glycogen. Creatine phosphate metabolizes easily and yields ATP quickly. Whereas glycogen is stored form of carbohydrate which yields energy more slowly. Therefore, initially, our bodies use creatine phosphate and then shift to glycogen. Within 60-90 seconds, the creatinine phosphate in the body is mostly utilized and then energy is produced by the use of glycogen in aerobic pathway. During areobic pathway, oxygen supply is sufficient and per cycle, it produces 32 molecules of ATP. However, when oxygen supply is limited or absent, the body will metabolize glycogen to lactic acid via fermentation and produce only 2 molecules of ATP.
Now consider the example: Kenny hikes all day at a steady pace therefore the supply of oxygen is sufficient for aerobic cellular respiration for ATP production. In this scenario, the oxygen debt is minimal and Kenny relies on aerobic respiration pathway to obtain energy. On the other hand, Janelle runs fast (100 meters in 13.5 seconds) and her cellular respiration would be on the compense of aerobic pathway initially which will be shifted to anaerobic pathway after the supply of oxygen is reduced/minimum. Janelle will heavily rely on the anaerobic pathway because running fast needs energy which cannot be provided via aerobic pathway easily. Therefore, Janelle's body will produce lactic acid and suffer from oxygen debt.
Answer:
Combined parenting leads to faster reproduction
Explanation:
Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.
During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.
Fertilization permits parental genes to be brought together. This causes variations in members of the same family.
Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.
